BRUSH Joseph D. Bates, West Springfield, Mass. 7 Application June '27,1931. Serial No. 547,448 5 Claims. (01. 15-202) This invention relatesto improvements inthe 'artof manufacturing brushes.

'The'principal objects of the invention are the provision of a novelmethod of making a brush of novel form which maybe removably carried by.a handle. The novel features of the invention will be explained inconnection with tooth brushes, but it will be understood that thoseskilled in'the artmay practicethe invention in connection with brushesand handles in general without departing from the spirit and-scope ofthe invention. I

It is desirable for sanitary and utility purposes to provide in a toothbrush, or in fact various brushes, 'a" handle and a plurality of brusheswhichmay be" removably carried by the handle.

In-this way a fresh brush may-be substituted for a used brush as oftenas desired To facilitate this according to certain special features ofthe invention brushes may be made at small cost, which brushes arereadily and easily inserted in or removed from a handle.

Numerous novel features and advantages of the invention willbehereinafter more fully referred to in connection with the followingdescription of the preferred form of the invention, which forillustrativepurposes merely is .shown in the accompanying drawingwherein:

Fig. l is a plan view'of a strip member which is coated or covered withbristles for forminga brush.

Fig. 6 is a side elevational view of the same with.

a brush inserted therein, and

Fig. '7 is a plan view of a modified form of the invention.

. Referring now to thedrawing vention will be described: g

In Fig. 1 there is shown av bristle support 2 in the form of a stripwhich is coated or covered with bristles 4. This bristle support 2 ispreferably made from some flexible or bendable material such'aspaper,'fabric, celluloid or the like and on it are deposited in somesuitable manner in detail the ina plurality of the bristles, all asshown. The bris-,

tles are arranged on the strip so that they extend outwardly from oneside thereof at least and they are secured to the strip in some suitableThe bristles may manner as by an adhesive material such as ceilulosematerial in sticky condition-like c'ollodion, which may be appliedeither to the strip or bristles, or both. I a

be the well known hair bristles or they maybe of some suitable syntheticf material, but will of course in all cases be of such a nature as willgive in a finishedbrushthe, desired brushing or scrubbingaction.Preferably the bristles used will be fibrous material, that is naturalvegetable fibers. These are well adapted for the practice of theinvention-because they are inexpensive and more or less porous.

The support and bristles will preferably be treated with some suitableantiseptic and the adhesive material for sticking the bristles there-'to will likewise include an antiseptic of some sort so as torender thewhole more or less antiseptic in nature. I

According to the modification of the invention shown in Figs. 2 and3, abristle supporting strip 6 is corrugated or providedv with spacedtransverse bristle receiving grooves or. depressions. Bristles 8 aredeposited-or: laid in these grooves as shown so as to be arranged inseparated groups. the strip by a suitable adhesive after the.mannerpreviously described. 1

The bristle supports described maytalze various forms and they may be ofvarious materials, while the bristles may be coated or laid thereonThese bristles may also be secured to in various ways and held thereonby various means. This is all to the end that the support with thebristles is in effect a support which-is coated or laid with bristlesextending outwardly therefrom.

A bristle support thus laidor coated with bristles may have disposedthereon or associated therewith an'additional strip of material represented by 10 in Fig. 4. This strip 10 willpreferably be of flexible,yieldable material such as fabric, paper or the like and such as will besuitable for contacting with the gumsofthe mouth for massagepurpos'es.,These strips, 10 extend outwardly for a distance from the bristlesupports at the same or aside opposite to that from which the bristlesextend or project.

A brush is formed "from a plurality of the tion as in Fig. 4. Arrangedin this way they provide a main body or brush assembly having bristlesextending from one side thereof and massage members extending from theother side. Of

course the strips may be arranged to extend transversely instead oflongitudinally as shown.

The strips 10 may be aflixed to the supports 2 and 6 at the time theyare coated or a plurality of the strips 10 and supports 2 and 6 may beassembled in various ways to provide a brush.

There may be as many of these bristle supports .in a brush as may bedesired and likewise any desired number of massage strips may beemployed. Adhesive material such as collodion or the like may be appliedto the adjacent faces of the superposed members and then the wholeassembly may be pressed in a die, or rolled, or in some manner subjectedto pressure or moulded to form a brush of predetermined size and form.This will be desirable in order that a plurality of brushes may beuniform in shape and size so as to fit in a holder.

In addition to securing these superposed strips together as described,it may in some cases be desirable to provide a binder or band '12 whichmay'extend around the brush body and be secured thereto in some suitablemanner as by applying suitable adhesive material thereto.

When these elements are pressed or moulded together and secured as theyare and then brought 'to some predetermined form and size and Whether ornot the brush embodies the outer binding band, the body formed in thisway will be suitable to insert in a handle of some sort.

The handle may take various forms, but in the form of the inventionshown in Figs. 5 and 6, it comprises a head member 20 which includes arectangular band 22 for receiving a brush. This band may be split at oneend and have complemental tapering screw members 24 as shown forscrewing into an internally threaded end of a handle 26. As the brush isinserted in the band 22 it will be embraced and retained therein byscrewing the handle and frame relative to one another so as to contractthe frame and thereby clamp the brush. The handle may take various formsand may be easily adapted to receive the brush, so that the brush may beinserted therein with facility.

According to the special features of the invention superposed layers ofmaterial coated or laid with bristles or threads and massage orseparating strips are arranged to provide brushes of variouspredetermined forms and shapes. When secured together by suitableadhesive material or otherwise and formed to provide a brush, saidbrushes'are rigid and in fact provide a unified brush structure which iseasily and readily inserted in a handle.

Various materials may be selected for the massage or separating stripsas well as for the bristle supports and even the bristles themselves asit is not intended to be limited to any particular'materials for thesevarious elements.

According to the modification of the invention shown in Fig. 7 a supportin the form of a strip is formed to provide a disc or ring 30 so thatbristles 32 will radiate therefrom. Such a strip as has been describedwhen made of paper, fabric or the like may be bent around and crimped ifnecessary in the center so as to give the desired disc. Such discs orrings may in themselves constitute brushes which may be affixed tohandles or rotatable elements. By coating or laying the bristles on thestrip and securing them thereto .a single handle may be used inconnection with a plurality of separate brushes which are adapted to beeasily and readily inserted in and removed therefrom.

In this way, since the brushes are inexpensive and easily inserted in orwithdrawn from the handle, it is possible to change brushes frequently,thereby as they become contaminated, soiled or worn, they may bereplaced with fresh brushes. This is all to the end that it is possibleto have for use at all times a brush which is in sanitary and healthycondition.

Having described the invention what I now desire to claim and secure byLetters Patent of the United States is:

1. As an article of manufacture, a unitary brush body comprising incombination, a plurality of bristle strip portions including a flexiblesupport having a plurality of fibrous bristles secured transverselythereon and extending outwardly from one side thereof and a plurality ofmassage strips, said massage strips being aroutwardly from one side ofsaid strip portions and a plurality of massage strip portions arrangedin alternate contiguous relation with the bristlestrip portions. 7

3. As an article of manufacture, a unitary brush body comprising incombination, a plurality of secured together bristle strip portionsincluding a flexible support having spaced transverse grooves with aplurality of fibrous bristles secured in said grooves, said bristlesextending outwardly from one side of said strip portions.
